Referring specifically to the drawings wherein like reference characters designate like or similar parts, thernold has a suitable base generally designated I0, which may be metallic and reinforced by suitable ribs E I. `Pallet supporting members ,I2 are disposed longitudinally of the base in `parallelism and have bolts i3 depending therefrom through openings in the base and are adjustably secured in said openings as to height by means of nuts Irl threaded onv the bolts.

Y The mold proper has parallel longitudinal side walls I5 and I6 and end walls I1.

Depending from the side Wall I5 are legs I8 50 i which arepivoted at I 9 longitudinally of the base, forraising and lowering. At opposite ends, said side wall `l5 and end walls I1 have intertting ears pivoted together byvvertical pins 20. The side wall` I t is separateV from the end walls litsl tively.

I1 and has depending legs 2| which are pivoted at 22 on a longitudinal axis, to the base IIJ, so that the 'wall I6 may be lowered.

The wall I6 also has longitudinal end extensions or ears at 25 which are engageable in notches 26 of latch levers 21, pivoted at 28 to the end walls I1 and having cam surfaces 29 co-acting with said extensions 25. In this manner, the mold is effectively held with the parts in rigid relation for a molding operation. v

A core member, preferably hollow and tapered is provided at 39 which is accommodated in tapered openings 3l and 3l', respectively, provided in the opposite end walls I1. and such corek member 36 has a handle at 32. This core member in turn, at suitable intervals throughout.v

With the structure described, a pallet is adapted to be `supported or built upon the strips I2, to close the bottom of the mold body consisting of the walls I5, I6 and I1. With the cores 36 and 35 in place, they concrete or cementitious material is placed in the body `and suitably tamped manually and leveled at the top of the body. When theconcrete or plastic body has suiiiciently set, the walls I6 and I1 may be detachedby lifting the levers 21, thereupon lowering the'wall I6, swinging the walls I1 away from each other and lowering the wall I5, following removal of the auxiliary cores` 36 and the main core 36. The cast block or tile may then be removed from the pallet or means supported 4on the strips I2.

Suitable designs or insignia 'may be embossed or provided in the block, by incorporating projections or depressions as at 39and 40 on the inner surfaces of the walls l and I6, respec- In addition, as shown in Figure 6, the length of the blocks may be regulated or blocks of any desired length or size may be provided by subdividing the space Within the mold through the application of partition panels 4I and l2 which are removably slidable in vertical grooves i3 arranged in the inner surfaces of the walls i5 and I6, the panels 4l and 52, respectively, being in engagement with the adjacent core members and applicable and removable in opposite directions.

Another type of partition is disclosed in` Figure 10 and is shown in use in Figure 9. This partition is used to limit the length of tiles beingcast, thas a wall 42 provided with a tapered opening 44, a notch at one end '45, and spacing flanges 45 preferably notched at 41. The core member 36 is adapted to be passed through and intimately fit the opening 44, with notch 45 accommodating the adjacent element 39. The flanges 46 at the notches l1 fit an adjacent auxiliary core member 36.

. Blocks or pillars are shown in` Figures 1l and l2 as at 48 and 49, being of different size and each grooved as at 59 and 5I, respectively, .to fit the core member 30 and also grooved at 52 and53, respectively,v to t the adjacent auxiliary core member 36. These pillars 48 and 59 may be used singly or in pairs at desired locations, to provide spaces, voids, or the like in the tile being cast, when desired to accommodate or iit parts usedin the construction employing the tiles produced according to the invention.

Attention is also called to the fact that the cores t 30 and 36 may be round in cross section o'r they may be square in cross section or of any other desired cross sectional area. For instance, as shown in Figures 13 and 14, said core members which are respectively designated 39 andk 36', are shown as square vin cross section, being of wood, metal or any other preferred material.

Referring now to the form of the invention disclosed in Figures l5 to 22, a form of machine is sho-Wn in which tile are made ofthe shape according to the preceding form of the invention, being made however in vertical position, usingmetal pallets, and wherein tamping is effected by means of a lever and associated parts in order to give a larger output for plant production,l than is true with the preceding form.

This second form of the invention has suitable supports 54connected by angle members 55 usually welded thereto and by a T-shaped angle member 56. On the supports 54 and associated parts, a mold 51 is carried and it has a vertical wall 58 welded or otherwise rigidly connected to the supports. It also has a side wall 59, parallel with the wall 58 and hinged to the supporting means as at 6I] so as to be able toswing downwardly in releasing molded blocks. Also, end walls 6I are provided, being pivoted at 62, to angle members 63 of the supporting means, so as to be capable of swinging downwardly to release cast blocks.

A pair of hollow removable core members 64 are employed, for instance having handles at 55 and such core members may be rectangular in cross section as shown, or of any other desired cross sectional configuration. These core members 64 are preferably longitudinally tapered, and they removably rest in openings 66 in the end walls 6I. Removable tubes or auxiliary cores 61 are vertically disposed and pass removably through openings 68 in the cores 64. Said auxiliary cores rest on longitudinally extending channel beams 69 welded at opposite ends to the supporting members 54.

Said auxiliary cores 61 pass removably through openings 19 in channel membersll of a top or follower plate 12.

In order to aid in properly positioning the auxiliary cores 51 and support pallets later to be described, spacing plates13 are employed, being removably secured in place by rods or bolts 15 secured together by screw threaded turnbuckles as at 15, the rods or bolts having heads at 16 and spacing sleeves 11 removably surround the rods between-the plates 13 The pallets are shown in the form of metallic plates 18, being in place vin Figure l5, and having openings at 19 accommodating the auxiliary cores therethrough. Said pallets have bosses, dowels or the like at 8U, struck-out therefrom,

Aaccording to the design ,desired for the block.

The mold space may be subdivided as desired. For instance, a removable longitudinal plate or partition 6I may be disposed in cut-outs 92 of the plates 13 and cross partitions 84 may co-act therewith, where desired, the same having struck-out bosses as at 85 toy aid in shaping the blocks.

It will be realized that the plastic material to be molded into the blocks is disposed about the cores between the pallets and side andend walls of the mold box 51 and that the head plate 12 is vertically movable in order to tamp the material.

According to the.V present embodiment, the 754 Such rods at their upper ends have notches `89 entered by the free ends of levers 9i, passing loosely through staples 92. Such levers 9! at their upper ends are pivoted at 93 to links 94, in turn pivoted at 95 to a plate 96 at projections or arms 9T thereof to which coil springs t8 are fas tened and which are also fastened to the top or head plate l2.

contractile coil spring I D4 is connected to the `stirrup and to the T-beam 5t.

As a result, it will be seen that upon placing the foot within the stirrup it!! and depressing` the same, the head l2' andupper pallet, will be' lowered or moved downwardly so as to tamp the plastic material in order to form theblocks, vthe spring l4 restoring the parts to normal position after each depression. After the blocks are formed, the walls 59, andlil` may b-e swung downwardly and the head plate 12 swung upwardly, and the core 64 and auxiliary core members 61 removed, as well as anypartitions 8l or 84, or

their equivalent, which have been used.

In order to normally urge one pallet 18 away from the other and properly position the same, coilexpansive springs HJG are employed which are housedin housing sections `lill and |08, The section |01 may be integral with or welded to the end wall Gland the sectionA l08 may simply abut the main core 64.

Various additional changes, variations and modifications may be resorted to within the spirit and scope of the invention as dened by the appended claims.
